Abstract (en)
[origin: US2022096693A1] A system for disinfecting an enclosed space includes an ultraviolet (UV) disinfection assembly, a sensor to detect occupancy in or entry into the enclosed space, and a controller. The UV disinfection assembly includes UV emitters. The controller controls operation of the UV emitters to carry out disinfection operations, each of a predetermined UV dose. The controller activates a disinfection operation in a first mode when: (1A) the sensor indicates no occupancy in or no entry into the enclosed space. The controller activates a disinfection operation in a second mode when: (2A) the sensor indicates no occupancy in or no entry into the enclosed space, and (2B) there is a qualified human input through a human-machine interface (HMI) in communication with the controller. The controller suspends or deactivates the disinfection operation when the sensor indicates occupancy in or entry into the enclosed space.
